To tell you the truth I have no idea (apparently!), but I will go get the POH and see what it says. The FTDK is NOT modified.
I would have said the V35B has a vacuum system cause people call the thing bolted to the engine a "vac pump". There is a dial labelled "suction" on the panel, and a light that I think is labelled "low suction".
Will go check and get back to you!
